Can't delete any records

I've just setup a new a workspace, and tried a delete the sample recods permanenetly, however it gave this error :

table "company" violates foreign key constraint "FK_ee066ddacfce46c9a7cb90edd1a" on table "person"

table "company" violates foreign key constraint "FK_ee066ddacfce46c9a7cb90edd1a" on table "person"

, i also created new records just to make sure it's not because it was created by "system", but its still the same,
